<p>I also applied after HS, (similar situation as you actually, didn’t apply first time). Just make sure you stay on top of everything and stay organized, because it’s not as easy as just asking your teachers; you have set aside time to go back and get everything from your counselor and teachers and everything. As long as you are a full time student at college (varies depending, but usually around 12 credits), it doesn’t really matter how many credits. Just do as well as possible (3.5+ is what the Academies really like). Good luck.</p>
